Thanks for responding. I should've tried it out on different hardware to
begin with, because 2.0 on an older AMD k6/450, the reader works just
fine. which means the problem lies most likely with my intel D845GBV
mobo.  perhaps a BIOS update... (too bad the software to flash the BIOS
requires a Windozes box! ARG.)
